[Some new aspects in the study of human cremations (author's transl)].

Thermally induced reactions of bone mineral are outlined. The shrinkage of cremated bones is due to sintering of bone mineral. In an electron microscopic study changes of bone structure caused by thermal treatment and sintered mineral units are described. The problems of estimating the shrinkage factor and the use of cremation weight for identification and discussed. There is a significant difference between mean weights of cremations of senile males and females. The absolute difference indicates, that cremation weight is not a useful criterion for identification. Even in cremated bones, cuts and saw marks can be detected.
